Physical properties
Hardness: 7 on the Mohs scale. Color: Light to dark green due to mineral inclusions. Luster: Vitreous to greasy, often with a shimmering effect known as aventurescence. Crystal structure: Trigonal. Cleavage: None. Specific gravity: 2.65.
Formation & geological history
Forms in metamorphic environments and hydrothermal veins, often as a variety of quartzite containing small plates of micaceous minerals like fuchsite. Geological age varies widely depending on the host rock formation.
Uses & applications
Widely used in jewelry, carvings, tumbled stones, and as a popular decorative or metaphysical gemstone.
Geological facts
Green Aventurine gets its characteristic glittering sparkle, known as aventurescence, from tiny reflective mineral flakes trapped inside the quartz matrix during formation.
Field identification & locations
Easily identified by its distinct green color combined with a subtle metallic glitter when turned in the light. Commonly sourced from India, Brazil, Russia, and the United States.
